False-colour SEM of human skin from a blister
False colour scanning electron micrograph of human skin from a blister on the palm of the hand (male). The skin on the palm is neatly arranged in ridges (not seen) with sweat pores (seen) appearing as miniature depressions tunnelling into the ridge- peaks. The external surface of skin, the epidermis, consists of keratinised, flattened layers of cells. Keratinization occurs when deposits of the fibrous protein keratin are layed down in the cells, causing them to toughen. This outer layer of cells is shed continuously (flaky) & is replaced by progressive movement & maturation of cells from the skin beneath. Magnification: X71 at 35mm size. Original is BW print P710/152

EDITORS COMMENTS
This false-colour SEM print offers a mesmerizing glimpse into the intricate world of human skin. Captured from a blister on the palm of a male hand, this scanning electron micrograph showcases the remarkable structure and composition of our body's largest organ. The neatly arranged ridges, invisible to the naked eye, become apparent in this image as they serve as housing for sweat pores. These miniature depressions tunnel into the peaks of these ridges, revealing an astonishing network within our skin. The outermost layer, known as the epidermis, is composed of flattened layers of keratinised cells. Keratinization occurs when fibrous protein deposits called keratin toughen these cells. As a result, our skin gains its resilience and protective qualities. Interestingly, this outer layer continuously sheds itself in a flaky manner and is replaced by new cells maturing from beneath. This perpetual process ensures that our skin remains fresh and rejuvenated over time. At 71 times magnification with a 35mm size frame, this photograph allows us to appreciate the intricate details that make up human skin at such close proximity. It serves as both an awe-inspiring visual spectacle and an educational tool for understanding the anatomy and functions of our remarkable epidermis.
